Travis Kelce has agreed terms with the Kansas City Chiefs on a contract extension in Thursday's second big NFL tight end deal, according to reports.

Kelce helped the Chiefs win the Super Bowl last season and his opposite number in that game, George Kittle, has secured a record-breaking pact with the San Francisco 49ers.

The Chiefs star's new contract does not quite match Kittle's but represents a boost for a player with two years remaining on his previous deal.

NFL Network's Ian Rapoport says Kelce is set to receive $57million across four years in his third NFL contract.

The five-time Pro Bowler has spent his entire career to date with Kansas City, who selected him in the third round of the 2013 draft.

Kelce was a key piece for the Patrick Mahomes-led champions in 2019, although the best season of his NFL career came the previous year.

He had 103 receptions for 1,336 yards and 10 touchdowns in 2018, building an effective partnership with MVP Mahomes.

The Chiefs quarterback has also committed his future to the franchise since their Super Bowl success, agreeing an unprecedented 10-year deal.
